# MediaCodec.BufferInfo

`public static final class MediaCodec.BufferInfo`
`extends Object` ``

java.lang.Object
↳ | android.media.MediaCodec.BufferInfo

Per buffer metadata includes an offset and size specifying the range of valid data in the associated codec (output) buffer.

## Summary

### Fields
`public int` | `flags` Buffer flags associated with the buffer.
`public int` | `offset` The start-offset of the data in the buffer.
`public long` | `presentationTimeUs` The presentation timestamp in microseconds for the buffer.
`public int` | `size` The amount of data (in bytes) in the buffer.

### Public constructors
`BufferInfo()`

### Public methods
`void` | `set(int newOffset, int newSize, long newTimeUs, int newFlags)` Update the buffer metadata information.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void` | `finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>` | `getClass()` Returns the runtime class of this `Object`.
`int` | `hashCode()` Returns a hash code value for the object.
`final void` | `notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void` | `wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

## Fields

### flags

    public int flags

Buffer flags associated with the buffer. A combination of `MediaCodec.BUFFER_FLAG_KEY_FRAME` and `MediaCodec.BUFFER_FLAG_END_OF_STREAM`.

Encoded buffers that are key frames are marked with `MediaCodec.BUFFER_FLAG_KEY_FRAME`.

The last output buffer corresponding to the input buffer marked with `MediaCodec.BUFFER_FLAG_END_OF_STREAM` will also be marked with `MediaCodec.BUFFER_FLAG_END_OF_STREAM`. In some cases this could be an empty buffer, whose sole purpose is to carry the end-of-stream marker.
Value is either `0` or a combination of `MediaCodec.BUFFER_FLAG_SYNC_FRAME`, `MediaCodec.BUFFER_FLAG_KEY_FRAME`, `MediaCodec.BUFFER_FLAG_CODEC_CONFIG`, `MediaCodec.BUFFER_FLAG_END_OF_STREAM`, `MediaCodec.BUFFER_FLAG_PARTIAL_FRAME`, and android.media.MediaCodec.BUFFER_FLAG_MUXER_DATA

### offset

    public int offset

The start-offset of the data in the buffer.

### presentationTimeUs

    public long presentationTimeUs

The presentation timestamp in microseconds for the buffer. This is derived from the presentation timestamp passed in with the corresponding input buffer. This should be ignored for a 0-sized buffer.

### size

    public int size

The amount of data (in bytes) in the buffer. If this is `0`, the buffer has no data in it and can be discarded. The only use of a 0-size buffer is to carry the end-of-stream marker.

## Public constructors

### BufferInfo

    public BufferInfo ()

## Public methods

### set

    public void set (int newOffset,
                    int newSize,
                    long newTimeUs,
                    int newFlags)

Update the buffer metadata information.

Parameters
`newOffset` | `int`: the start-offset of the data in the buffer.
`newSize` | `int`: the amount of data (in bytes) in the buffer.
`newTimeUs` | `long`: the presentation timestamp in microseconds.
`newFlags` | `int`: buffer flags associated with the buffer. This should be a combination of `MediaCodec.BUFFER_FLAG_KEY_FRAME` and `MediaCodec.BUFFER_FLAG_END_OF_STREAM`. Value is either `0` or a combination of `MediaCodec.BUFFER_FLAG_SYNC_FRAME`, `MediaCodec.BUFFER_FLAG_KEY_FRAME`, `MediaCodec.BUFFER_FLAG_CODEC_CONFIG`, `MediaCodec.BUFFER_FLAG_END_OF_STREAM`, `MediaCodec.BUFFER_FLAG_PARTIAL_FRAME`, and android.media.MediaCodec.BUFFER_FLAG_MUXER_DATA
